Comparison of the blood pressure management between sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists

Abstract

The cardiovascular and renal protective effects of sodium-glucose cotransporter 2 inhibitors (SGLT-2is) and glucagon-like peptide 1 receptor agonists (GLP-1Ras) are enhanced by low/controlled blood pressure (BP). However, the BP-lowering efficacy of SGLT-2is and GLP-1Ras have not been compared directly. We compared the rates of achieving target BP with SGLT-2i and GLP-1Ra treatments in Japanese patients with type 2 diabetes mellitus (T2DM). This retrospective study included 384 SGLT-2i- and 160 GLP-1Ra-treated patients with BP > 130/80 mmHg before treatment. Inverse probability weighting methods using propensity scores were used in this study. The integrated odds ratios (OR) for BP control rates were calculated and clinical changes were analyzed using a generalized linear model. SGLT-2i treatment resulted in significantly higher BP control rates than that in the GLP-1Ra treatment (integrated OR = 2.09 [1.80, 2.43]). Compared with GLP-1Ra, SGLT-2i treatment demonstrated significantly larger decreases in diastolic BP, mean arterial pressure, and body weight (- 3.8 mmHg, P = 0.006; - 4.1 mmHg, P = 0.01; and - 1.5 kg, P = 0.008, respectively) and increased annual estimated glomerular filtration rate (eGFR; 1.5 mL/min/1.73 m²/year, P = 0.04). In T2DM patients with poorly controlled BP, compared with GLP-1Ra, SGLT-2i treatment significantly improved BP management and increased eGFR.
